Gearbox increases drive train performance by 10%
4th Quarter 2015
Hydraulic systems & components
Bosch Rexroth’s Hydrotrac GFT 8000 gearbox gives a 10% increase in drive train performance on larger mobile working machines. Ideal for use in harsh, rugged environments including African mining operations, they have two- and three-stage combined planetary gearing with axial piston motors to match the needs of heavy and bulky mobile working machines such as trucks and excavators.
An optional internal brake reduces the installation space needed, while adhering to the safety specifications for worldwide roadworthiness certification. The mechanical planetary drives in these transmission units transfer the torque from the hydrostatic drive to the wheels or tracks. Variable axial piston motors or fixed-displacement axial piston motors operate in either an open or closed circuit.
The higher fluid capacity of the motors and the higher hydraulic pressures, along with the exact matching with the two- and three-stage planetary drives, boost torque and therefore performance by approximately 10%. This improves travel capacity significantly. The optional integrated multi-disc brake inside the unit requires minimal maintenance and is designed for protection against soiling.
All units are delivered as complete assemblies. Vehicle manufacturers can select a smaller nominal size to achieve the same output, which also saves on installation space. Due to the platform’s modular concept, OEMs can vary the drive torques and transmission rations, closely matching them to the vehicle used. Two models in the 8000 series, which achieve nominal torques of 20 and 30 kNm, are available off-the-shelf, and an additional seven models are currently being rolled out to the market.
